Royal Hats 
You seem to have forgotten Princess Anne and her (number? It’s somewhere between 2 and 7, pretty sure of that much) black fur pillboxes!
There are lots of royal twin hats waiting in the wings to be highlighted here! Stay tuned.
Great article!! I can’t believe Princess/Queen Beatrix has quintuplets! She is probably the member of a royal family who has the most stable and predictable hat style. Wild guess: did she try many hat styles in her young years and decided this particular one was the best suited for her?
